Surprising to find "fuckin" in the OED, just casually dropped in there to help us understand the second part of the third definition of "midget," which is "A person notably deficient in the quality or ability indicated by the preceding adjective."

(Sorry, I can't provide links that go into the OED, but you could buy it: here.)

ADDED: Fascinatingly, the word "fuckin" — according to the OED — predates "fuck" as an English word. It appears in 1528, written in a margin: "O d fuckin Abbot." ("O d" is presumed to mean "damned.") Now that I've looked up "fuck," I like some of these other quotes:

1598 J. Florio Worlde of Wordes, Fottere, to iape, to sard, to fucke, to swive, to occupy.

a1749 A. Robertson Poems (?1751) 256 But she gave Proof that she could f—k....

1776 Frisky Songster (new ed.) 36 O, says the breeches, I shall be duck'd, Aye, says the petticoat, I shall be f—d.
1931 H. Miller Let. 16 June in Lett. to Emil (1989) 133 Tell her to go fuck a duck!
1955 M. Brando in T. Williams Five O'Clock Angel (1991) Epil. 122, I feel like a bucket of stork shit for having fucked things around so.

The cultural significance of The Sopranos was sometimes a bit subtle. The irony of at least a few of the scenes though was pretty sharp.

One of my favorites is when Phil deviates from toasting the manliness of Tony's crew by lambasting his captain Vito with every epithet he can imagine to describe the disgust he feels for his homosexuality. Sensing the inappropriateness of the moment, one of Phil's captains attempts to restrain him by reminding him that the wine he's drinking makes him "emotional". Phil responds by saying that it's because he's got an empty (f-word) stomach.

My favorite line from The Sopranos:"Cunnilingus and psychiatry brought us to this." - Tony says to his wife at after a small war starts within the family and he and his Uncle Junior have tried to kill one another.

Verb infinitives in both German and Old English were conjugated with the suffix "-en", if I'm not mistaken, so that 1528 quote sounds about right. It was probably before our awful spelling conventions were standardized, in any event - or right about that time. "To fuck" in German is "ficken".

"Probably cognate with Dutch fokken to mock (15th cent.), to strike (1591), to fool, gull (1623), to beget children (1637), to have sexual intercourse with (1657), to grow, cultivate (1772), Norwegian regional fukka to copulate, Swedish regional fokka to copulate (compare Swedish regional fock penis), further etymology uncertain: perhaps < an Indo-European root meaning ‘to strike’ also shown by classical Latin pugnus fist (see pugnacious adj.). Perhaps compare Old Icelandic fjúka to be driven on, tossed by the wind, feykja to blow, drive away, Middle High German fochen to hiss, to blow. Perhaps compare also Middle High German ficken to rub, early modern German ficken to rub, itch, scratch, German ficken to have sexual intercourse with (1558), German regional ficken to rub, to make short fast movements, to hit with rods, although the exact nature of any relationship is unclear."

"I've always assumed that the work "fuck" originated in an attempt to mimic the sound producing by fucking!"

Me too! The closest the OED comes to acknowledging that is "Many alternative theories have been suggested as to the origin of this word. Explanations as an acronym are often suggested, but are obviously much later rationalizations."
